Title: Improvements in fluid pressurizing devices and systems employing same
IPC: F25B31/00
Filed: 1966-02-24
Abstract: 1,142,605. Steam generators; refrigerating. CONDUCTRON CORP. 24 Feb., 1966 [24 Feb., 1965; 4 March, 1965], No. 8078/66. Headings F4A and F4H. [Also in Division F1] A gas generator comprises a chamber 31 into which liquid is introduced via check valve 37, until a float valve 57 closes outlet 51 and the chamber pressure reaches the inlet line pressure, a continuously energized heating element 45 then causing the liquid to boil, and the vapour produced being discharged through check valve 38 until sufficient liquid has boiled away for the float to drop to open outlet 51 and depressurize the chamber, the cycle then being repeated. A liquid forcing embodiment is described (see Division F1) in which the discharge port and valve 38 are adjacent the bottom of the chamber. In Figs. 4 and 10 (not shown), a throttled by-pass port (95) is uncovered by the liquid to cause sudden depressurization of the chamber, and hence falling of the float to open the main depressurizing port 51. In Fig. 9 (not shown), heat losses are reduced by locating heater (77) in a well (82) of the main chamber (75), float (55) being guided by a member (83). In Figs. 13 and 14 (not shown), centrifugal force replaces gravity for moving the float to its depressurizing position. Four segmental chambers in a rotor (162) have floats (55) movable radially to control depressurizing valves (125) and inlet valves (121). The float alternatively may be biased by acceleration or magnetic forces. In a refrigeration application, Fig. 15, a mixture of a pumping fluid and a refrigerating fluid is vaporized and circulated by the device 30. The mixture of vapours generated in chamber 31 is discharged under pressure through check valve 210 to a condenser 200 where both vapours are condensed. On passing through an expansion valve 202 and an evaporator 201, only the refrigerating fluid is vaporized, the mixture of liquid and vapour returning to chamber 31 via check valve 37. Vapour discharged through depressurizing port 61 is condensed in condenser 204 and returned to the inlet. In another refrigeration application, Fig. 16 (not shown), a single fluid is used, the generated vapour being supplied under pressure from the device (30) to a turbine (220) driving a compressor (221). The exhaust from the turbine and the discharge from the compressor are fed to a common condenser (200), expansion valve (202) and evaporator (201). Vapour from the evaporator is fed back to the compressor inlet (223) and some of the liquid from the condenser is returned to the vapour-generating device for driving the turbine.

Title: Improvements relating to polymerization catalysts and their use
Inventor: COOPER WILFRID
IPC: C08F36/04
Filed: 1962-03-02
Abstract: A polymerization catalyst comprises (1) an organometallic compound, a metal hydride, an organometallic hydride, or an organometallic halogen compound of a metal of Group I, II or III, of the Mendel<\>geeff Periodic Table and a component (2) consisting of two halides in intimate admixture, each in a lower than normal valency state, and selected from halides of two different metals of "A" sub-groups IV to VII, and VIII, of the Periodic Table. Component (2) is made by reacting under anhydrous conditions a halide of a metal of IVa, Va, VIa, VIIa or VIII, in its highest normal valency state, with a metal of Group I to III, or a hydride, or an organo-metallic compound of such a metal to reduce the halide to a lower halide, mixing the lower halide with another higher halide of another metal of Group IVa to VIIa or VIII, and reacting this other halide with the same classes of reducing agents as used in the previous reduction, thereby reducing this other halide to a lower halide.  The polymerization may be effected in presence of diisopropyl ether. Specified higher halides are TiC,4, ZrCl4, WCl6 and VCl4. Exemplified catalysts systems are Al(C2H5)3 and a mixture of TiCl3 and VCl3.  In the examples, the following polymers are prepared, polyisoprene, polyethylene, a copolymer of ethylene and propylene, a copolymer of ethylene, propylene, and bicyclopentadiene, poly-pentadiene-1,3, and a copolymer of isoprene and butadiene.ALSO:<PICT:1024179/C1/1> Mixtures of two halides each in a lower than normal valency state, and selected from two different metals of "A" sub-groups IV to VII, and VIII, of the Mendel<\>geeff Periodic Table, are made by (1) reacting under anhydrous conditions a halide of a metal selected from one of the above groups, and in its highest normal valency state, with a metal Group I to III, or a hydride, or an organometallic compound of such a metal, to reduce the halide to a lower halide, and (2) mixing (1) with another higher halide of another metal of Groups IV(a) to VII(a), or VIII, and reducing this other halide with the same classes of reducing agents as used in (1).  When TiCl4 is used in step (1), the TiCl3 formed is converted into the alpha-form by heating to between 135 DEG  and 225 DEG  C.  The following preparations are exemplified, (1) a mixture of TCl3 and VCl3 is obtained by dispersing TiCl4 in liquid paraffin, treated with Al(C2H5)3 for 30 minutes, heated to 170 DEG  C. for 1 hour, cooled, VCl4 added, Al(C2H5)3 added, and mixture heated for 1 hour at 120 DEG to 135 DEG  C., and (2) a mixture of TiCl3 and VCl3, by dispersing TiCl4 in liquid paraffin adding Zn(C2H5)2, stirring for 1 1/2 hours, heating the brown solution of beta-TiC.3 at 210 DEG  C., cooling to room temperature, adding VCl4, adding Zn(C2H5)2 dissolved in liquid paraffin, and after about 3/4 hour, recovering by centrifuging the mixture.

Abstract: 1,221,342. Moulding plastics substances. XEROX CORP. 20 Feb., 1968 [11 Sept., 1967], No. 8149/68. Heading B5A. [Also in Division G2] A method of making replicas of a surface deformation image comprises the steps of (a) forming a first generation negative master by applying a layer of hardenable material against the surface deformation image, hardening said layer and stripping it from said surface and (b) forming a second generation positive replica by casting a liquefied film forming material against the negative master and transferring the cast replica to a support member. The hardenable material, which must be inert to the deformation image surface is preferably a curable silicone rubber or may be a low melting point alloy, gelatine or polyvinyl alcohol. The film forming material is a plastics dissolved in a solvent, e.g. polystyrene in toluene, polymethyl methacrylate in methyl ethyl ketone or ethylene dichloride, or cellulose acetate butyrate in ethyl acetate. The surface deformation image may be formed as a frost or relief image, or preferably as a phase hologram, or a deformable, insulating, thermoplastics layer. A negative metal master may be prepared by spraying silver on to the second generation replica, electroplating the silver layer with nickel to form a supporting layer, and withdrawing the metal layers from the cast replica. This master may be used as a short run stamper, or its surface may be passivated chemically and a positive nickel replica formed thereon by electroplating. This nickel master may be used for long run hot stamping of preheated thermoplastics e.g. cellulose acetate films, the preheating temperature being about 200 F., the stamping pressure 400-6000 psig, the stamping master temperature 120-300 F., and the pressing time 1-10 seconds.
